This book is for those that use Excel at work and who want to use the advanced features of Excel but don't have the time to have extensive training. It takes you through each task (as all Brilliant books do) and describes everything you could want to find out, for example:

how to use the macro recorder
how to take that recorded code and turn it into something useful that will really help you day to day
how to automate reports and design applications

Users will then improve their Excel skills so they can in the end save a lot of time and get more done.
